A weather station using an Arduino Uno is a project that utilizes various sensors to measure atmospheric conditions such as temperature, humidity, and pressure. The Arduino Uno is a microcontroller board programmed to read and process the data from these sensors and display the information on an LCD display.

The project typically involves connecting the sensors to the Arduino Uno using jumper wires and programming the board to read the data from each sensor. The temperature sensor measures the ambient temperature, while the humidity sensor measures the amount of moisture in the air. The pressure sensor measures the atmospheric pressure. Once the Arduino Uno has collected the data, it can display the results on an LCD display. The display can show the current temperature, humidity, and pressure readings, as well as additional information such as the time and date.
